¥ 25. R. Latiro‘uius L’Hérit. Vhe broad-leaved Buckthorn. 
Identification. L’Heérit. Sert., 5. t.8. ; Dec. Prod., 2. p. 26.; Don’s Mill., 2. p. 32. 
ce L’Heérit. Sert., 5. t. 8. 5 Dend. Brit., t. 11.; Willd. Abbild., t. 100.; E. of PL, No. 2886. ; 
our fig. 210. ; and the plate of this tree in Vol. IT. 
Spec. Char., §c. Leaves elliptical, acuminate, quite 
entire, lineated with 12 or 15 lateral nerves; younger 
leaves and calyxes villous. Flowers hermaphrodite. 
(Don’s Mill., ii. p. 32.) A deciduous shrub, with 
the habit of a low tree; a native of the Azores, on 
the mountains of St. Michael. Introduced in 1778. 
It flowers in July, and the berries which succeed 
them are either red or black, both colours appearing 
on the same plant. The leaves are larger than those 
of any other species; and the whole plant is remark- 
able for its robust appearance, and the conspicuous 
opposite nerves, which proceed from the middle of 
the leaves. It deserves a place in every collection. 
There is a tree of it at Syon 15 ft. high. In London, 
plants are from 1s. to ls. 6d. each. At Bollwyller, 
1 franc and 50 cents; and at New York, 50 cents. 


i 
App. i. Hardy Species of Rhamnus not yet introduced. 
R. amygddlinus Desf. Atl., 1. p. 198., a native of the north 
of Africa, in the fissures of rocks, where it grows to the height 
of 3ft., and produces berries used for dyeing yellow, like those 
of &. saxatilis. 
R. per'sictfolius Moris. Stirp. Sard, 4to, fasc. 2.,a native of Sar- 
dinia, and probably only a synonyme of R. amygdalinus. 
R. prunifolius Smith Prod. Fl. Gree., 1. p. 157., a native of 
Crete, on the highest mountains, and probably only a variety 
}} of one of the preceding 
Z sorts. 212 
R. Sibthorpianus Schult. 
Syst., 6. p. 286, A. pu- 
bescens S7zbth. Fl. Grec., 
t. 239., a native of Mount 
Parnassus, and nearly al- ‘S 
lied to #. alpinus, and R. (3 
Frangula. 
R. Purshianus Dec. 
Prod., 2. p. 25. (fig. 211.), 
the &. alnif dlius of Pursh 
but not of L’Héritier, a 
shrub, growing to the ¢7% 
height of 6 ft., native of / 
North America, on the * 
; banks of the Koorkoosky. 
eee, Pers., a native of Galicia, on the banks of rivers, where it grows to the height 
of 6 ft. 
.. R. minutiflorus Pursh, a native of the sea coasts of Carolina and Florida. 
The following species probably belongs to another genus ; but, not having seen the plantiwe can 
say nothing about it of our own knowledge. 
R, carpinifolius Pall. Ross., 2, p, 24. t. 60., Willd. Spec., 1101., and N. Du Ham., vol. iii. p. 40., 
(fig. 212.) is said to bea treeresembling the hornbeam. Pallas says that it abounds in the calcareous 
mountainsof Kutais, in Russia, but that he never saw its flowers. It may possibly be a Planera. 

App. il. Half-hardy, or Green-house, Species. 
R. integrifolius Dec. Hort. Monsp., #. coriaceus Nees’s Hore Phys., p. 114. t. 22., is a shrub, a native 
of Teneriffe, on the highest peak, where it attains the height of 2ft. ; introduced in 1822. and, doubt- 
less, half-hardy. 
R. prindides L’Heérit. Sert., 6. t.9., Zizyphus licidus Mench is a shrub, growing 10 ft. high 
in Africa, at the Cape of Good Hope; introduced in 1778. 
R. celtidif dlius Thunb. is a native of the Cape of Good Hope, not yet introduced. 
R. crenuldtus Ait. Hort. Kew., 1. p. 263., is a shrub, growing to the height of 6 ft. on the moun- 
tains of Teneriffe ; in culture in British green-houses in 1778. 
R. serrulatus H. B, et Kunth Nov. Sp. Amer.,7. p. 51. t. 617., is a shrub, growing to the height 
of 6 ft. in Mexico, not yet introduced. 
R. microphgllus Willd. is a trailing shrub, a native of Mexico, resembling #. oledides, intro- 
duced in 1823. 
R. umbellatus Cav. Icon., 6. p. 2. t. 504., isa shrub, growing 6 ft. high in Mexico. 
R. tenuifdlius Moc. in Dec. Prod., 2. p. 26., is a native of Mexico, of which little is known. 
Besides the above, there are some doubtful green-house species, all of which it would be desirable 
te procure, in order to prove their degree of hardiness, and assist in reducing this genus to order.
